Rhemaxos was an ancient king who ruled to the north of Danube around 200 BC and who was the protector of the Greek colonies in Dobruja, receiving a tribute from them in exchange of protection against outside attacks. It appears that the links with the Greek cities lasted a rather long time, as several treaties have been found.
Some historians have suggested that he was the chieftain of a Dacian tribal union on the Romanian Plain. Others said he was a Scythian king.
His son Phradmon allocated 600 horsemen to defend the city of Histria at the request of Agathocles, son of Antiphilos.[1][2]
